A contribution to the hazards assessment at Copahue volcano (Argentina-Chile) by facies analysis of a recent pyroclastic density current deposit
(Elsevier Science, 2016-11)
We recognised and interpreted a recent pyroclastic density current (PDC) deposit at the Copahue volcano (Southern Andes), through a field survey and a sedimentological study. The relationships between the behaviour of the ...
Towards the definition of AMS facies in the deposits of pyroclastic density currents
(Geological Society of London, 2014-01)
Anisotropy of magnetic susceptibility (AMS) provides a statistically robust technique to characterize the fabrics of deposits of pyroclastic density currents (PDCs). AMS fabrics in two types of pyroclastic deposits ...
Subaqueous eruption-fed mass-flow deposits: Records of the Ordovician arc volcanism in the northern Famatina Belt; Northwestern Argentina
(Elsevier, 2014-01)
This study is focused on the analyses of a Chaschuil section (27° 49′ S–68° 04′ W), north of the Argentina Famatina Belt, where Ordovician explosive-effusive arc volcanism took place under subaerial to subaqueous marine ...
Architecture and pyroclastic succession of a small Quaternary (?) maar in the Pali Aike Volcanic Field, Santa Cruz, ArgentinaAufbau und pyroklastische Abfolge eines kleinen quartären (?) Maars im Pali Aike Vulkanfeld, Santa Cruz, Argentinien
(E Schweizerbartsche Verlags, 2006-09)
An approximately 200 m long, 3 m thick continuous outcrop of a near vent crater rim tephra sequence from a young phreatomagmatic volcano of the Pali Aike Volcanic Field (Santa Cruz Province, Argentina) is one of the few ...
